Sounds worth a look. I have now tested 4 of the 5 Laserjet IIs I had and 
three give the 50 report, one works and one is buried under so much junk 
I cant yet get to it.  The LJ-3 is just plain dead and the LJ-4 also has 
the 50 error.  But now that I have one running the 5 bad units are going 
out to the curb on saturday (after I check the fuser bulb idea you 
suggested).  One day I will check out that last LJ-2....when this one 
goes out.  I kind of hope the bulbs are NOT the problem, I need the 
space in the garage....#8-)
